“It was lots of fun because in other films all of the actors are dreading it,” Green told THR. “But that one was kind of a little break, because most of our scenes are intense – love, hate – but it was like a dance, like Ken and Barbie making love.”

In Dark Shadows, Green plays Angelique Bouchard, a former chambermaid who curses Depp’s character to an eternity as a vampire after he rebuffs her love. Their gymnastic lovemaking aside, Green explained that she enjoyed the challenge of making Angelique sympathetic while also embracing her over-the-top vindictiveness.

“I tried to find the reason why she’s doing evil things,” Green said. “She’s misunderstood – she’s had her heart broken and she just takes her revenge by turning Barnabas into a vampire and locking him in a coffin.

“That’s what we all do when we’re upset,” she said with a laugh. “She’s damaged, but quite a bit mad – obsessed with Barnabas.”

Green said that she also enjoyed her collaboration with costume designer Colleen Atwood and director Tim Burton on Angelique’s look, which begins to change as Barnabas re-enters her life. “In ‘72 she looks perfect,” she said. “It’s all too perfect, like a mask. And then when Barnabas reemerges in the 70s, she starts freaking out because he’s her weakness.

“She can’t control all of this and so she starts cracking up mentally -- and also physically.”
